Request to add a CRUD app in app showcase

[AbrarJahin]

Hi @MarkPieszak ,

Currently, we have a REST API in here-

https://github.com/MarkPieszak/aspnetcore-angular2-universal/blob/master/docs/RESTAPI-ENTITY.MD

So, we can easily add a CRUD example in here-

https://github.com/MarkPieszak/aspnetcore-angular2-universal/blob/master/src/AspCoreServer/Server/Api/UserController.cs

So, we can use this to create a CRUR app in Angular2 on this page-

https://github.com/MarkPieszak/aspnetcore-angular2-universal/blob/master/src/Angular2Spa/Client/containers/rest-test/rest-test.component.ts

And also create a service folder for storing all API services like this-

For being a template, I think only 1 API is OK for us for our CRUD-

https://github.com/MarkPieszak/aspnetcore-angular2-universal/blob/master/docs/RESTAPI-ENTITY.MD

I think u got me @MarkPieszak

If we can add a CRUD in our template, it will be more useful and more acceptable for the developers.

Because then it will be a perfect starter pack I think.

Waiting for your suggestion @MarkPieszak
